The guys at Two Brothers Racing have developed a full exhaust system for the Grom. The system increases the horse power of the Grom from 8.65 to 9.5, which translates to a 8.5% boost in power. Torque is similarly increased from 7.64 ft-lbs to 8.04 ft-lbs.
The TBR S1-R gets rid of the catalyst and shaves 5.5 lbs off of the Grom.
The carbon fiber can and exhaust pipes will cost you $529.98.
What do you guys think? Would you put this on your Grom?
